With environmental and economic concerns, this study shows how to enhance the energy dissipation of flow along an inclined drop. The goal of this research is to develop a novel way for evaluating aquatic health on inclined drops, as well as a mechanism for dissipating surplus flow energy utilising fish-pass components. Three varieties of basic inclined drops and inclined drops without fish-pass features were used in 81 distinct studies with a flow rate of 200-600 lit/min. The researchers discovered that when the relative critical depth grows, the energy dissipation values increase and the downstream Froude number decreases. The metrics of relative downstream depth, relative duration of the hydraulic jump, and relative aeration length all climb when the relative critical depth rises. Model F7 dissipates the most energy, whereas Model F2 has the longest flow aeration duration and relative downstream depth. The employment of fish-pass components decreases the downstream Froude number greatly, in addition to boosting aeration and dispersing the destructive force of the flow. As a result, these components may be useful for scouring the bed and channel walls, as well as strengthening the stability of downstream structures. Non-hole fish-pass components were also shown to be useful for enhancing energy dissipation, but hole elements are more efficient for designs with environmental goals.
